<ul>
<li>修改侧边栏参考官方文档<a target="_blank" rel="noopener" href="https://panjiachen.gitee.io/vue-element-admin-site/zh/guide/essentials/router-and-nav.html#%E9%85%8D%E7%BD%AE%E9%A1%B9">路由||侧边栏</a></li>
<li>本项目侧边栏和路由是绑定在一起的，所以你只有在 <code>@/router/index.js</code> 下面配置对应的路由，侧边栏就能动态的生成了</li>
<li>其中的<code>@</code>就是<code>src</code>目录，你可以在<code>vue.config.js</code>中看到</li>
</ul>

<ul>
<li>一般侧边栏有两种形式即：<code>submenu</code> 和 直接 <code>el-menu-item</code>。 一个是嵌套子菜单，另一个则是直接一个链接。如下图：<img src="https://cdn.jsdelivr.net/gh/xiaoliblog/image@5838e5aa38f25d519dc4f4238ba11b87a3dac421/2021/04/26/d55e94d443df74706e2c573d09217d8e.png"></li>
<li>在 Sidebar 中已经帮你做了判断，当你一个路由下面的 children 声明的路由大于<code>&gt;1</code> 个时，自动会变成嵌套的模式。</li>
<li>如果子路由正好等于一个就会默认将<strong>子路由</strong>作为根路由显示在侧边栏中，若不想这样，可以通过设置在根路由中设置<code>alwaysShow: true</code>来取消这一特性</li>
<li>在路由中修改如下，图标可以去<a target="_blank" rel="noopener" href="https://panjiachen.github.io/vue-element-admin/#/icon/index">官方文档</a>查找</li>
